mathnode··on Amazon Aurora Now Available
It's linked in the article, here is more links:

mathnode··on Amazon Aurora Now Available
Absolutely not. Galera operates on synchronous transactions, Aurora operates at the storage layer.

Amazon Aurora – New Cost-Effective MySQL-Compatible Database Engine for Amazon RDS

* https://aws.amazon.com/blogs/aws/highly-scalable-mysql-compa...

It's an engine for MySQL.

Aurora Database Architecture by Amazon Web Services:

mathnode··on Amazon Aurora Now Available
A Postgres to MySQL client mapping middleware is probably the holy grail? I think it's been done in the JDBC space.
mathnode··on Amazon Aurora Now Available
The closest thing to Aurora would be Clustrix; scale at the storage level behind a single entry point.

Aurora is more than just RDBMS as a service.

mathnode··on Amazon Aurora Now Available
It's just a storage engine, albeit a very good one (I was on the beta); storage engines act as a plugin to the mysql/mariadb server layer, and are typically just a separate binary.
mathnode··on Ask HN: ETL solutions for developers?
Python, and its various libraries including Pandas, and odo.
mathnode··on Intro to RenderMan for Blender
Rendering, is a job in itself. There are people who do nothing but develop looks and write shaders all day everyday, and others who create and manage distributed rendering pipelines.

Cycles is great, but just like Mental Ray, in other applications, it's part of another package. Sure you can run them headless, but why? When there is something that is made for it that is so well documented and has great support solely for that purpose.

Rendering features aside, it's a great business and architecture choice.

mathnode··on JSON Labs Release: Native JSON Data Type and Binary Format
JSON support is also provided by the CONNECT storage engine, which I think is much simpler.

https://mariadb.com/kb/en/mariadb/connect-json-table-type/

e.g:

  SQL > CREATE TABLE junk.j1 (a int default null)
  ENGINE=CONNECT DEFAULT CHARSET=utf8
  table_type=JSON
  File_name='j1.json';

  SQL > insert into junk.j1 (values) (1);

  $ ls $(mysql -NBe "select @@datadir")/junk
  db.opt	j1.frm	j1.json

  $ cat $(mysql -NBe "select @@datadir")/junk/j1.json
  [
	{
		"a": 1
	}
  ]
I use this for generating config files, and getting data into pydata tools; no need for a database driver, which is interesting.
mathnode··on Goat Simulator Post Mortem
I would absolutely buy and play Goat Tycoon.
mathnode··on Lisp as an Alternative to Java (2000) [pdf]
n*2 words: I don't get it?
mathnode··on NewSQL overview
Slide 27. VoltDB.

Or use posgres-xc, or mariadb 10 with galera and maxscale. Postgres has JSON storage. MariaDBB has dynamic and virtual columns, and the CONNECT engine which can now directly create new or edit existing JSON files using the SQL interface, instead of dedicated functions for JSON manipulation.

mathnode··on Windows 10 for Raspberry Pi 2
I had (optimistically) predicted the way to to ARM desktops was with Steam and gamers coming over to Linux and the majority of code bases being more portable they could cross-compile games to Linux on ARM.

But this could work too!

mathnode··on AWS Lambda
It's no different from stored procedures and triggers in a database, or a shell language on an operating system. At some point you will have to invest time creating logic, for your purpose, on somebody else's system.
mathnode··on The SQLite Database File Format

mathnode··on First set of Android apps for ChromeOS
Your thing, doesn't relate to his thing. Not one bit.
mathnode··on Show HN: Convert CSV files into MySQL insert scripts
I am not putting 1TB+ per table dumps of data into a strangers website what can be done with a bit of sed or a script in ${LANGUAGE}.

Loader from Several Nines, is a tool for doing parallel loads of CSV into MySQL and MariaDB https://github.com/severalnines/loader

Mydumper is a threaded dump and load tool for MySQL/MariaDB. https://launchpad.net/mydumper

Tungsten Replicate can do batch load replication into any external datasource http://docs.continuent.com/tungsten-replicator-3.0/deploymen... So long as you have a script for it: https://code.google.com/p/tungsten-replicator/source/browse/...

EDIT: A fun extra, https://mariadb.com/kb/en/mariadb/documentation/storage-engi...

mathnode··on Nvidia Jetson TK1 Reviewed
I am wondering if you can add an external GPU via the mini pcie interface:

mathnode··on Show HN: GameDevs.com, a social news site for game developers
There isn't actually any game development related content on there. It's just games business news, if that.

GameDev, r/gamedev, tigsource, and polycount are already great resources.

mathnode··on Paint.Net 4.0 is now available
Pixelmator for mac, it also has a vector editor. The new version also allows for 16bit editing, which GIMP doesn't do yet (but Krita does).
mathnode··on Improved default settings for Linux machines
In fact any RDBMS of a similar design to Ingres requires a larger shmax value including, postgres, sybase axe, and informix.
mathnode··on Official UK singles chart to include streaming services
We should probably just work on a procedural media algorithm and call it "pop cache"; but it's not really a cache it just generates the same garbage over and over again with slight iterations and adapts to current trends in news, politocs, social economics etc. This would save a ton of I/O. Once again, computer science is the ring master for the Bread and Circus.

Just automating Max Martin really.

mathnode··on Poll: Are you moving to the Amazon Fire Phone?
No. Because my iPhone helps me to be productive. It's not a shopping cart (there's an app for that should I wish).
mathnode··on Microsoft Paying Bloggers to Write about Internet Explorer
The thing is, it's boring. We don't care! We have had good browsers for years! Too late to the party as always MS.
mathnode··on The 12 step process to download Microsoft SQL Server Express 2014
It's the same for Sybase ASE/SQL Anywhere, DB2, Informix, etc. Several hoops to jump through, various registration details (I hit Forgot Password, everytime); big companies with several products and one massive site made of smaller sites to serve the needs of many people and products.

Never fear windows guys and gals, your favourite open source databases that are massively scalable are readily available, and nobody from sales will give you a call to discuss options:

* https://downloads.mariadb.org

* http://www.enterprisedb.com/downloads/postgres-postgresql-do...

(if I put my tongue any further into my cheek I am going to make a hole!)

mathnode··on Poll: What database does your company/you use?
Sybase ASE and Sybase SQL Anywhere are not listed, yes they are different.

If you are going to have column stores, you should have InfiniDB.

And if you are going to have SQLite, you should also list MS SQL Server Compact. MS Access is also a viable option, also DBase and Filemaker.

Clustrix and NuoDB should also be in the list if you are listing NewSQL systems like VoltDB.

I am sure there are others :S as a DBA would be interested what businesses or systems only back onto column stores without a traditional RDBMS or a modern NoACID system.

mathnode··on What's left of NoSQL?
> NoACID

Perfect!

mathnode··on MariaDB 10
Using the CONNECT engine you can read (and I think write?) data to ODBC data sources. This is essentially a very cheap IBM Federated system...it's even written by one of their original devs.
mathnode··on NHS England patient data 'uploaded to Google servers', Tory MP says
That's nearly 4.5TB if it was gzipped plain-text.
mathnode··on Linux Design Tools: High-end Design on a Low-end Budget?
Gimp? No.

Krita? Yes.
